GLENDORA, Calif. (AP) — A destructive wildfire above foothill suburbs northeast of Los Angeles is largely reduced to smoke and scattered flames, but the charred landscape remains too dangerous for about 2,000 people to return home.

Fire officials say flare-ups occurred Friday within the 2½-square-mile burn area but none escaped the perimeter.

Some 3,700 residents of Glendora and neighboring Azusa were ordered to leave their homes at the height of the fire Thursday, when five homes were destroyed and 17 other structures were damaged.
